Hi
We went hiking at the Coon Rapids Dam above the dam between eight a.m. and eleven a.m. and saw the long tailed duck again.  I couldn’t get any good photos but I have a link at the end of this to show you that at least it is still there.
In addition to the Long Tailed Duck we saw a couple of bald eagles, one mature, one immature, a red tailed hawk, some goldeneye, ring neck ducks, two hooded mergansers, two coots, lesser scaup, a single wood duck flying by plenty of Canada Geese, no redheads today that I could tell.  It was cold and windy. . Below is a link to a couple of photos.
